Tuff Shed review: Delivery service & poor follow up customer service

I purchased my shed from Tuff Shed located in Pacoima, CA. The door that was delivered with the Shed was warped and locking the shed up is difficult. I have made 6 calls to Tuff Shed within the past week and have received 0 call backs. Sales rep. Gave me his card with personal cellphone number. I was told at time of purchase. to contact the sales rep. Anytime if I had any problems or complaints. THIS WAS A LIE...
